PM Harold Wilson, UK and JWs. Anyone know if this headline was to be taken literally? Satire?

[JW Insider]

I am not trying to sell an item on eBay. This item has been listed up there for quite some time, and the seller is in the UK. 

I was only wondering if anyone knew why the reference to JWs was on the cover. Did he actually say something like what's on the cover?

The description. says: The front cover features Harold Wilson - Wislon Joins Jehovah’s Witnesses. Wilson is saying: “I cannot be a Christian and Prime Minister". 

Note that they spelled Jehovah's Witnesses correctly, but not Wilson.

The Awake! mentions him a couple of times:

*** g74 8/8 p. 30 Watching the World ***
Church and State
◆ The recently appointed Archbishop of Canterbury, Donald Coggan, now heads the (Episcopalian) Anglican Church of England. Embarrassingly, a Methodist appointed him! Why? That is the religion of England’s prime minister, Harold Wilson, whose duty it is to make such appointments.
 

*** g74 5/8 pp. 11-12 What Hope for Britain’s Economic Recovery? ***
The Campaign
The Conservatives (Tories), led by Heath, campaigned under the slogan, “Who Rules Britain?” They claimed that militant union extremists were bent on imposing their will on the nation in defiance of Parliament. Heath asked the country’s voters to return him to power with a strong majority in Parliament, to give him authority to deal with the problem of inflation.
His Labour Party opponents, led by Harold Wilson, lost no time in calling it a phony election, telling Mr. Heath that, in spite of a working majority in Parliament since 1970, he had signally failed to deal with inflation. They castigated his campaign against union militants as a “Reds under the bed” campaign meant to scare the unwary into line.
Throughout the three-week campaign an endless stream of opinion polls consistently put Heath’s Conservatives in the lead, with Labour a few percentage points behind. An unexpected element was the steady resurgence of the Liberal Party, which, after fifty years in the political wilderness, was shown to be gaining substantial support.
 

As an aside, this makes me wonder if the Awake! would ever return to doing long (4-page) articles reporting on various political issues and campaigns.

At issue, sarcasm.

Seemed like sarcasm or satire. I have never seen the magazine. But the author may have known our take on neutrality, or thought it was well-known enough to make use of as the key to the satire. If people didn't know that JWs were neutral and didn't hold political offices, then this line would potentially fall flat.

To me, then, it showed that the author knew JWs pretty well something beyond no war and no flag salute. Otherwise, I was thinking there might have been something more specific in the article that tied something he said or did to JWs.
